The correct Answer is:
To solve the question regarding how nucleotides are joined together in a simplified version of a nucleic acid chain, we can follow these steps: ### Step-by-Step Solution: 1. **Understanding Nucleotides**: - Nucleotides are the building blocks of nucleic acids (DNA and RNA). Each nucleotide consists of three components: a nitrogenous base, a pentose sugar (ribose in RNA and deoxyribose in DNA), and a phosphate group. 2. **Structure of Nucleic Acids**: - In a nucleic acid chain, nucleotides are linked together to form a long chain. The structure of nucleic acids can be simplified to show how these nucleotides connect. 3. **Identifying the Linkage**: - The connection between nucleotides occurs through specific chemical bonds. In nucleic acids, the phosphate group of one nucleotide connects to the sugar of the next nucleotide. 4. **Type of Bond Formed**: - The bond that forms between the phosphate group of one nucleotide and the sugar of the next nucleotide is known as a phosphodiester bond. This bond is crucial for the backbone structure of nucleic acids. 5. **Conclusion**: - Therefore, in a simplified version of a nucleic acid chain, nucleotides are joined together by a **phosphodiester linkage**. ### Final Answer: Nucleotides in a nucleic acid chain are joined together by **phosphodiester linkage**.
